"I can understand the man who denies miracles altogether: but what is one to make of people who will believe other miracles and 'draw the line' at the Virgin Birth? Is it that for all their lip service to the laws of Nature there is only one natural process in which they really believe? Or is it that they think they see in this miracle a slur upon sexual intercourse (though they might just as well see in the feeding of the five thousand an insult to bakers) and that sexual intercourse is the one thing still venerated in this unvenerating age? In reality the miracle is no less, and no more, surprising than any others."
C. S. Lewis, Miracles, chapter XV, paragraph 10.
